BACKGROUND For epidemiological and therapeutic reasons early diagnosis of superficial viral infections is crucial. Conventional microbiological techniques are expensive, time consuming, and not sufficiently sensitive. In this study impression cytology techniques were evaluated to analyse their diagnostic potential in viral infections of the ocular surface. METHOD A Biopore membrane device ins...

Latent herpes simplex virus (HSV) has been demonstrated in the trigeminal ganglia of experimentally infected rabbits between episodes of spontaneous ocular recurrence. In three experiments reported here, the normal pattern of recurrence was modified by manipulation of the trigeminal nerve and ganglion. Temporary retrobulbar disruption of trigeminal nerve function in chronically infected animals...

We developed a murine model of ocular herpes simplex virus (HSV) disease which is particularly suited for testing stromal keratitis because most animals show some evidence of infection. Using this model, we characterized the ocular disease patterns caused by ten recent low-passage clinical isolates of HSV-1, as well as those caused by the established laboratory strains HSV-1 KOS and HSV-2 333. ...

We report the frequency and type of infectious ocular complications following orthotopic liver transplantation (OLT) and review diagnostic and therapeutic strategies. During the period September 1988 through November 1994, 684 patients underwent OLT at Mount Sinai Hospital (New York). Nine orthotopic liver transplant patients (1.3%) developed ocular infections: Candida albicans endophthalmitis ...

This report evaluates the role of interaction between glucocorticoid-induced tumor necrosis factor receptor (GITR) and GITR ligand (GITR-L) in the immuno-inflammatory response to infection with herpes simplex virus (HSV). Both GITR and GITR-L were transiently upregulated after ocular HSV infection, on antigen-specific T cells and antigen-presenting cells, respectively, in the draining lymph nod...

PURPOSE To study the effect of aminoguanidine (AMG), an inhibitor of nitric oxide production, on the ocular infection of Balb/c mice with herpes simplex virus (HSV) type 1 strain F and HSV-2 strain G. METHODS Animals were treated with different amounts of AMG (0.5, 0.1, and 0.05 mg/mouse) by topical application in the eye from postinfection (PI) days -2 through +5, considering 0 the day of in...

abstract background and aims: herpes simplex virus (hsv) is a common cause of corneal disease and is the leading infectious cause of corneal blindness among developed nations. this study is aimed to provide an estimation of the incidence of herpes simplex virustype-1, 2(hsv1, 2) and varicella zoster virus (vzv) in tears and swab from eye infection by polymerase chain reaction (pcr) in eye disea...

PURPOSE To report the clinical outcomes of deep anterior lamellar keratoplasty (DALK) when sterile gamma-irradiated acellular corneal tissues (VisionGraft) are used in combination with amniotic membrane transplantation (AMT) for intractable ocular surface diseases. METHODS The medical records of fifteen patients who had DALK with AMT were retrospectively reviewed. Indications for surgery incl...

Episcleritis and scleritis are both inflammatory disorders of the eye may have underlying systemic disorder precipitating them. Therefore a thorough clinical examination laboratory investigations needed to rule them out. Systemic conditions that been associated include rheumatoid arthritis, Wegener’s granulomatosis, vasculitis, lupus erythematosis, sarcoidosis, spondyloarthropathies, tuberculos...

Herpes zoster (Shingles; Zona) is an acute infectious skin disease that is caused by the reactivation of varicella zoster virus (VZV). After the initial infection (chickenpox) or vaccination, the virus remains inactive or latent in the dorsal root ganglia (DRG); when decreasing cell mediated immunity (CMI) occurs, the virus is reactivated from a latent phase to a lytic phase and frequently repl...
